The paper reported that the U.S. Attorney’s Office executed a search warrant at the Colonial Drive condominium of William Thomas, 64, on Thursday morning. Christina DiIorio-Sterling, a spokeswoman for the U.S. Attorney’s Office in Boston, said Thomas was charged with receipt of child pornography.

Details of the arrest have not been released.

Thomas’ arrest comes a week after the arrest of Dr. Richard Keller, the former medical director for Phillips Academy in Andover. The 56-year-old is in federal custody following his Sept. 13 arrest on one count of receiving child pornography.

Keller works at Children's Hospital Boston and is an instructor at Harvard Medical School. Both put him on leave after his arrest.
